Heavy Neutral Lepton searches at an ICARUS-like detector using NuMI beam
Animesh Chatterjee, Josu Hernandez-Garcia, Albert De Roeck
The discovery of non-zero neutrino masses points to the likely existence of multiple SM neutral fermions. When such states are heavy enough that they cannot be produced in oscillat…
The Present and Future Status of Heavy Neutral Leptons
Asli M. Abdullahi, Pablo Barham Alzas, Brian Batell +42
The existence of non-zero neutrino masses points to the likely existence of multiple SM neutral fermions. When such states are heavy enough that they cannot be produced in oscillat…
GeV-scale neutrinos: interactions with mesons and DUNE sensitivity
Pilar Coloma, Enrique Fernandez-Martinez, Manuel Gonzalez-Lopez +2
The simplest extension of the SM to account for the observed neutrino masses and mixings is the addition of at least two singlet fermions (or right-handed neutrinos). If their mass…
Global Bounds on the Type-III Seesaw
Carla Biggio, Enrique Fernandez-Martinez, Manuele Filaci +2
We derive general bounds on the Type-III Seesaw parameters from a global fit to flavor and electroweak precision data. We explore and compare three Type-III Seesaw realizations: a…
New Weinberg operator for neutrino mass and its seesaw origin
Josu Hernandez-Garcia, Stephen F. King
We consider a new Weinberg operator for neutrino mass of the form involving two different Higgs doublets with opposite hypercharge, where $\tilde{…
IceCube bounds on sterile neutrinos above 10 eV
Mattias Blennow, Enrique Fernandez-Martinez, Julia Gehrlein +2
We study the capabilities of IceCube to search for sterile neutrinos with masses above 10 eV by analyzing its disappearance atmospheric neutrino sample. We find that IceCube…
Non-Unitarity vs sterile neutrinos at DUNE
Josu Hernandez-Garcia, Jacobo Lopez-Pavon
Neutrino masses are one of the most promising open windows to physics beyond the Standard Model (SM). Several extensions of the SM which accommodate neutrino masses require the add…
Completely general bounds on Non-Unitary leptonic mixing
Josu Hernandez-Garcia
We derive constraints on the mixing of heavy right-handed neutrinos with the SM fields in the most general Seesaw scenario where the heavy neutrinos are integrated out. Among the e…
Non-Unitarity, sterile neutrinos, and Non-Standard neutrino Interactions
Mattias Blennow, Pilar Coloma, Enrique Fernandez-Martinez +2
The simplest Standard Model extension to explain neutrino masses involves the addition of right-handed neutrinos. At some level, this extension will impact neutrino oscillation sea…
Global constraints on heavy neutrino mixing
Enrique Fernandez-Martinez, Josu Hernandez-Garcia, Jacobo Lopez-Pavon
We derive general constraints on the mixing of heavy Seesaw neutrinos with the SM fields from a global fit to present flavour and electroweak precision data. We explore and compare…
Loop level constraints on Seesaw neutrino mixing
Enrique Fernandez-Martinez, Josu Hernandez-Garcia, Jacobo Lopez-Pavon +1
We perform a detailed study of the importance of loop corrections when deriving bounds on heavy-active neutrino mixing in the context of general Seesaw mechanisms with extra heavy…
Radiative corrections to from three generations of Majorana neutrinos and sneutrinos
S. Heinemeyer, J. Hernandez-Garcia, M. J. Herrero +2
In this work we study the radiative corrections to the mass of the lightest Higgs boson of the MSSM from three generations of Majorana neutrinos and sneutrinos. The spectrum of the…
